Application4 filed March `8,

particularly adapted for making compressed paper rolls or'cylinders.

aper rolls of the lrind in question are made 1oy.pressing annular sheets of paper her to form a thick Walled cylinder of ideraole length and it isnecessarythat .z the materia. 'forming the roll be made dense and homogeneous throughout. Tov insure. homogeneity the paper rolls are built up in iat is, a number of annular s heets L ci, A oi ")aper .are threaded on a mandrel and coing essed after which successive 4batches orsun'eiies of annular sheet-s are added and eempressedI until .the roll is builtup to the lengfn. t is the object of this invention to provide ay press which canbe easily and rapidly manipulated andfwhich will facilitate the operations necessaryhbetween the several pressings during rthe manufac-` ture of such rolls. Preferably hydraulic means are employed for operating the press. i in the accompanying drawings forming part of' this specification lthere is illustrated one specificV embodiment of the invention;v in said drawings: y y

A table or support 13. is y slidably mounted on the platform l12, this platform andthe extension la'thereof bef. ing'provided with guide; Ways 14' in which thetable 13 `is adapted to slide. y y

u.For moving they table back and forth in its guideways the following means, are prof vided.l` At each edge'the table 13 is bored `longitudinally to form cylinders` 15, Within` which stationary plungers 16 are mounted, these plungers at their outer ends being rigidly secured tothe platform 12. A passage is formed vin each of the plungers 16, Which )a's'sao'es extend the entire lenoth of thel n p z3 l y plungers and communicate. at `their outer ends with apipe 18 for supplying'pressure fluidtothe cylinders ,The tablelB is alsoprovided substantially at itseenterivith alongitudinally extending @cylinder 19 lwhich is radapted to receive a stationary plungerQO, thelattergbeing rigidly secured to the extension 12a of the platform 12. 4 rllhe vplungerh() also has a passage extending throughout its entire-length by Which pres`- sure fluid is supplied to the cylinder 19, this passage communicating `with a pipe 21 for supplying pressure fluid. y y l lJhe cylinders yj 15 and 19 kare preferably made of thesame size and receive pressure 'iuid from'a common source. rlhe cylinder 19 is preferably suppliedwith pressure fluid at' all times Which servesl toy hold the table 13 normally in its inner position. 'When pressure fluid is. supplied to the cylindersv 15 the constant pressureinthe cylinder 19 is oversome and the tablev ismoved toits outerposition.` When thek pressure 'Within 'thelcylinders 15y is relieved the table will be v 'automatically returned to its position above the plunger 11 by means .of the constant pressure maintainedin the cylinder 19. 'The details of the system for supplying` the pressureliuid and of the valve mechanism for controlling the supplyof such pressure Huid to the plunger 1 1 and to the ycylinders 15 and 19 are not illustratedjas these may be of Aany approved type and arranged in any convenient position. A desirable arrangle'- ment for supplying pressure' fiuid to the cylv inders 15and19 is-shown in the drawing. in

l the length of the table 13.- 10' which the pipes 18 and21 are connected, respectively, to pipes 18a and 21 which receive pressure fluid from the cylinders 18b and 21b through which they slide.

A block or foot-step 25 is bolted to they upper surface of thentable 13, this block, as shown particularly in Figure 4, having al U-shaped recess or opening parallel to which is pressed thereon and which restsv upon the top of the block 25, and against which the paper is compressed in forming theroll. f

A plurality of vertical columns 30 are iXedly supported in any suitable manner in the base 10, preferably three of these columns being employed. The upper ends 'of these columns are held in rigid relation by means of a. spider 31 secured thereto. rllhecolumns 30 are threaded at their upper ends for a considerable distance and such threaded portions are engaged by threaded bushingsor nuts 32 which are suitably journaled in 'a cross head 33. Each ot said bushings 32 at its upper end is provided with a worin wheel 311- suitablysecured thereto Vwhich worm wheels are arranged to mesh with worms 35 secured to shafts 36, journaled in suitable bearings on the cross head 33. These shafts are rotated in any suitable manner as by means of a reversible motor 37 connected -to a shaft 38 provided with worms 33a meshingwith worm wheels 36a on the sha-.tts 36. lt will be apparent from the foregoing that when the threaded bushings 32 are rotated by means of the motor 36 the cross head 33 will be caused to movetoward or from the table 13.

When vthe table 13 is moved along the guideways 14, as heretofore described, the mandrel 26 mounted thereon. will, of course, be moved'with the table. ln other words, the mandrel will be moved in a direction transverse to its own axis, or laterally ot the cross head 33. To permit such lateral movement of the mandrel the cross head 33 is provided with a U-shaped slot Aor opening i10 as will clearly appear from Figures 1y and 2 of the drawings. rllhis slot or opening 40 is arrangedparallel to the direction of movement of the table 13 so that.

when the table is moved outwardly the mandrel can pass through the opening 40 to aiposition beyond thecross head 33.

During the operation ot compressing the the cross head.

ypaper it is desirable to place an annular plate similar to the plate 27 upon the upper end of the mandrel and such a plate is indicated at 27a on the drawing. lt-desired, the cross head 33 may also be provided with a block 33a similar to block 25 for bearing against the plate 27a. e .In operation, assuming the cross head 33 in its upper position and the table 13v in its outer position, a mandrel, suc-h `as 26, is mounted centrally on the latter, the lower end of `the mandrel extending into the U shaped opening ofthe block 25 and the plate 27 resting upon this block. A quantity of paper rings are now threaded on the mandrel and the metal' plate orl ring 27a` is placed on top of the kpaper rings. The iluid pressure in the cylinders 15 is thenreleased y when the constant pressure inthe cylinder 19v causes the table to move automatically to its inner position beneath the cross head `33. The motor 37 is then started-inl a direction to lower the cross head until its lower face or the block 33LL securedthereto rests on the plate 27aV supported by the paper rings. At such time the mandrel 26 projects upwardly lin the slot or opening` 40ct the cross head 33. then applied .under the ram or plunger 11 to raise the tab-le 13 and, asa. result, the paper rings are pressed togetherbetween the rings27 and 27i surrounding the mandrel.- The pressure undenthe ram 11 is F luid pressure is e' held for aV short time and is then released I to lower the table 13.` rlhe latter is then moved to its outer position supplying pressure fluid to the cylinders 15 during which movement the upper endoit4 the mandrel passes through ther U-shaped opening y y 40 or the cross head 33 until it is tree :trom The neXt batch of paper rings arenow threaded on the maiidrel, the metal ring .27'nl in the meantime being removed. During the operation et threadw ing the new supply of rings on the mandrel the motor 37 is started to raise the cross head suthciently to clear the second batch ot'rings. .The operations are repeated until the required length of paper roll is obtained.

By constructing the cross head as' described, it will be understood that the 'mandrel can be moved laterally to a-posiion yclear of the cross headn ,and it is, therefore, unnecessary to move the latter upwardly to clear the upper endv ot the' mandrel.

the top of' thecolinnns.l The` entire con-A struction, therefore, is ,so arranged Vas to facilitate the operations incident to form? ing the rolls or cylinders.
